Wizard installer — Test 1

Test build for Andre and other testers. This is not the stable release.
Installer 1.4.0 candidate; game files remain 3.0.8 Lau. No DBC edits.

1. Close WoW completely.
2. Download LauSetup.zip, right-click it and choose Extract All.
3. Open the extracted LauSetup folder and double-click LauSetup.exe.
4. Choose the folder containing WoW.exe, then click Next.
5. Check the fixed Patch-Y HD or Patch-Y Non-HD selection. Extras start off; enable what you want. Already installed maps are kept. Click Next.
6. Review your choices and the automatically included files, then click Install upgrade. Wait for Finished and click Finish.

Use Interface language at the top if automatic detection is wrong. The choice is remembered. Next does not download or change game files. Keep LauSetupBackups; Restore previous install restores the originals.

Linux testers use the same ZIP with the documented existing Wine environment and LauSetup.sh; follow the bundled README.

Please report whether detection, Back/Next, option summaries, language switching, installation and Restore work as expected. Include the exact message and a screenshot if something goes wrong.

Windows and normal-user Wine regression tests passed, with all ten interface languages and small-window layouts checked. In-game testing remains separate.

Tracks #26 and draft PR #28. Stable release remains 1.3.0 while the wizard is tested and coordinated documentation/publication is completed.
